The legality of cybersex will vary, as certain internet service providers and chat rooms will monitor and prohibit cybersex from occurring in their services.
In "real cybering" personas often remain in character throughout the entire life of the contact, to include evolving into phone sex, and meatspace encounters while in character, as a form of improvisation, or, nearly, a performance art.
Therefore, many jurisdictions will treat cybersex as engaging in sexual practices.
This will in turn give rise to the situation where cybersex can be illegal.
Cybersex can oftentimes employ the use of webcams, by which those engaging in cybersex can physically view the other participants.
Cybersex, often simply referred to as cyber, is intended to be undertaken for sexual stimulation and arousal, regardless of whether or not real life masturbation is taking place.
One approach to cybering is a simulation of "real" sex, when participants try to make the experience as close to real life as possible, with participants taking turns writing descriptive, sexually explicit passages.
